Abstract (en)

[origin: EP3709286A1] A liquid crystal display panel and a gate drive circuit. The liquid crystal display panel (30) comprises: a plurality of pixel units arranged in a matrix manner (Pixel 11-Pixel 24); a plurality of scanning lines (G1-G5), each two of the scanning lines corresponding to the same row of pixel units and being alternately connected to pixel units in the same row of pixel units; a gate drive circuit (31); a plurality of data lines (D1-D3), each of the data lines being connected to two adjacent columns of pixel units, respectively; and a data drive circuit (32), wherein gate drive signals on the two scanning lines corresponding to the same row of pixel units have different drive capabilities. By means of the method, the difference in brightness on the display panel (30) can be reduced, and the display effect can be improved.
